There is no uncertainty when the pipeline is damaged irreparably.
Destroying the pipelines doesn't benefit neither germany nor russia.
Russia has been reducing gas supplies through Nord Stream 1 for a number of months.
In June, it cut deliveries through the pipeline by 75% - from 170m cubic metres of gas a day to roughly 40m cubic metres.
In July, Russia shut it down for 10 days, citing the need for maintenance. When it reopened, the flow was halved to 20m cubic metres a day.
In late August, it shut down Nord Stream 1 entirely, blaming problems with equipment. The pipeline has not been open since then.
If Nord Stream is shut down suddenly through “force majeure,” a sudden uncontrollable stop that is the fault of neither party, then Russia can void its obligations toward European stakeholders without legally breaking contracts, thus dodging the many penalties in doing so.
